Schneider Electric TeSys D Contactor LC1D38 | 3-Pole (3NO), AC-3 38A, <= 440V Ultra-Compact Industrial Motor Control Switch

Schneider Electric TeSys D 3-Pole Automatic Contactor (Model: LC1D38) is an industrial-grade, maximum-capacity magnetic switching device engineered to deliver robust, high-reliability operational control over heavy electric motors, localized commercial ventilation blocks, and severe inductive loads. Fully optimized for high-stress $AC-3$ utilization categories, this premium contactor manages a continuous operational current of 38A for motors up to 440V AC, providing the exact electrical calibration and structural resilience required to run standard 18.5 kW (25 HP) 3-phase inductive induction motors at 380V/400V.

Belonging to Schneider Electric’s world-renowned TeSys D flagship range, the LC1D38 pushes technical boundaries by accommodating its heavy 38A rating inside a compact 45mm width footprint. It features a high-integrity 3NO (3 Normally Open) main power pole architecture, coupled with integrated auxiliary contacts (1NO + 1NC) as standard to facilitate immediate electrical interlocking, safety feedback loops, or automated PLC/BMS control logic. Engineered with advanced arc-chute grids and high-grade silver-nickel alloy contact tips, it withstands aggressive, high-frequency duty cycles under elevated ambient temperatures. Fully compliant with international safety benchmarks including IEC/EN 60947-4-1, this block mounts easily onto standard DIN rails or mounting plates, establishing itself as the definitive professional specification for heavy industrial water pumps, exhaust fan arrays, large conveyor lines, and commercial elevator panels across Egypt.

Note: The complete structural part number varies depending on your required control circuit voltage coil (e.g., LC1D38M7 for 220V AC, LC1D38P7 for 230V AC, LC1D38B7 for 24V AC, or LC1D38BD for 24V DC).

Key Technical Features:

• 38A Operational Current (AC-3): Precision-calibrated for continuous-duty starting, reversing, and stopping of heavy 3-phase induction motors up to 440V.

• AC-1 Resistive Load Rating: Capable of handling a massive 50A (at <= 60°C) for non-inductive resistive applications like industrial heating blocks and large lighting loops.

• Maximum Power-to-Size Ratio: Delivers an impressive 38A capacity within the standard 45mm compact frame size, maximizing space efficiency inside packed enclosure boxes.

• Built-in Auxiliary Contacts: Features integrated 1NO + 1NC auxiliary links for seamless electrical interlocking, remote status feedback, and automation telemetry.

• Robust Multi-Standard Screw Terminals: Heavy-duty power terminals ensure consistent, high-torque clamping, eliminating dangerous cable overheating and wire arcs under continuous site vibration.
